Specification of Letters Patent.

Patented July 21, 1914.

Application filed February 12, 1912. Serial No. 677,223.

To all whom it may concern:

Be it known that 1, MAX Bosnian, a citizen of the United States, and aresident of New York, county and State of New York, have invented acertain new and useful Improvement in Fire-Escapes, of which thefollowing is a full, clear, and exact specification.

This invention relates to a class of devices or fire escapes adapted tobe used upon a building for permitting the occupants to safely departtherefrom in emergency.

My invention has for its object primarily to provide a form of fireescape designed to be constructed upon the exterior of a building, orother structure, and employed especially to permit a large number ofpersons who may occupy the building to quickly and safely departtherefrom when imperiled by fire, or other danger. These advantages areattained mainly by providing a fire escape in which a chute composed ofa number of communicating sections are employed in successivearrangement upon a building, and which are inclined downwardly inopposite directions from story to story of the buildiinother object ofthe invention is to provide a form of chute having an undulating mainchute or bottom whereby the speed of the person sliding theredown willbe partially checked so as to obviate injury from impact at their exitfrom the chute.

Still another object of the invention is to provide an entrance to eachsection of the chute at each story of the building in order to permitpersons in various parts thereof to depart simultaneously; and a furtherobject of the invention is to provide at each entrance a branch racewaywhich converges with the main raceway so that persons passing into thechute from the lower stories of the building will not obstructthe'downward passage of the persons in the chute.

A still further object of the invention is to provide a form of chuteupon the sections of which may be constructed a stairway adapted toserve as a means of escape from the building as well as permittingfiremen or others to gain convenient access to the upper parts thereofin emergency.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawing,which form a part of this specification, and will then be pointed out inthe claim at the end of the description.

In the drawing, Figure 1 is a front elevation of a building with oneform of fire escape embodying my invention applied thereto, part of saidfire escape being broken away. Fig. 2 illustrates a rear end view,partly broken away, of the fire escape, and Fig. 3 is a top plan of thefire escape.

The device or fire escape 10 has a chute 11 which may be composed of aplurality of communicating sections 12, 13, 14 in accordance with thenumber of stories of the building, as 15, upon which it is applied. Allof the sections of the chute 11 are preferably alike in formation, eachbeing substantially rectangular in shape, and may be constructed so asto be suitably supported in staggered arrangement in opposite directionson a downwardly incline from one story to the other story of thebuilding, in order to provide a curve or bend at each meeting point ofthe sections so as to avoid too precipitous a passage through the chuteespecially when the fire escape is applied to high buildings, or otherstructures.

As a means to partially check the speed of persons when sliding throughthe, sections of the chute 11 so as to obviate injury from impact whendeparting from the exit, as 16, at the base of the chute, each sectionthereof is provided with a bottom in the form of irregular curves, orwide corrugations, as illustrated, whereby an undulating main raceway,as 17, is provided. By providing the irregular curved bottom orundulating raceway 17 as well as the curved or rounded junctures of thesections of said raceway it is evident that a person may slide down thechute from a great height with comparatively little or no danger ofbeing injured.

Upon the building, as shown in the drawing, may be provided a number ofplatforms, as 18, 19, 20, one of which is suitablv supported so as to bein proximity to the windows, or other means of exit, of each floorthereof. Upon the top platform is an inclosure 21 which is preferablvspaced from the wall of the building, and said inclosure has a doorway22 leading to the main raceway 17. Upon each of the platforms 18 and 19is a similar inclosure 23 and 2 1 which are likewise spaced from theinclosures 23 and 24L and communicating with the main raceway 17 byconverging therewith as shown at 27, at thetop of I each section of thechute is a branch racej way-28 and 29 adapted to permit persons to enterinto the main chute after passing into the inclosures 23 and 24: fromthe lower platforms and escaping by way of the main raceway at the sametime as the persons from the upper part of the building are sliding downthe main raceway.

' Upon each section of the chute 11 is a stairway 31, 32 which areadapted to serve as means for permitting the occupants of the buildingto escape therefrom in'emergi ncmandsaid stairways may also be used byfiremen or others in gaining convenient access .to the upper parts ofthe building as occasion requires.

' I t e ressing s ipl I h e bodied the preferred form of my invention,but I do not wish to be understood as limiting myself thereto, as I amaware that modifications may be made therein without departing from theprinciple or sacri- Y A fire escape comprising a series of coveredchutes, said chutes being arranged in series to-form alternately andoppositely inclined flights with reference to a vertical line; the chuteof the higher flight joining the chute of the next lower flight .by acurved bottom surface to form a'continuous slide from top to bottom ofthe fire escape; and anentrance to each chute,said entrance leading tothe chute of the next lower flight and the mouth of said entrance beingwholly above the termination of the chute of the next higher flightthereby preventing flames and smoke from being drawn into the fireescape.
